Why Radon Levels Stayed High: Mystery Crawl Space Fix

We installed a radon mitigation system in this home, but something didn’t add up. When radon levels stayed higher than expected, we brought in fellow mitigator Mitch Kelly for a second look. He spotted something we missed: a hidden crawl space. After adding a suction point, radon levels dropped just as we had hoped. A big thanks to Mitch for the assist!
